Present study was performed to identify the effects of SNS WOM characteristics on attitude and purchase intention as perceived in restaurant participants and to confirm the moderating effect according to SNS receivers' characteristics on formulated model. Survey method was employed to consumers who are using SNS to find restaurant foods through convenience sampling method in Seoul area. A total of 250 surveys were distributed and 230 were used for analysis, after excluding missing and unusual data. The results from this study are as follows. First, vividness of SNS WOM characteristics had a greater effect on attitude of restaurant food than timeliness, but the consensus and neutrality of SNS WOM characteristics have no significant effect on attitude of restaurant food. Second, SNS receivers characteristics found to moderate the relationships between vividness and timeliness of SNS WOM characteristics and attitude. However, SNS receivers characteristics did not have a moderating role relationships between consensus and neutrality of SNS WOM characteristics and attitude. Third, attitude of restaurant food had a significant effect on purchase intention.

The development of Social Network Service (SNS) has brought many positive changes to the ways people communicate, interact and share information. However, using the SNS does not always leads to in a positive results, particularly when it is addictively used. In fact, the addictive use of SNS results in many negative effects in our society. Recently, SNS users feel negative emotions such as expecially stress and fatigue while using SNS. Thus, the purpose of this study is to empirically examine antecedents of user fatigue on SNS, which can be explained by the degree of Individual, environment and SNS characteristics. This study also examines consequences of user fatigue on SNS. Lastly, we examine the moderating effects of Habit among SNS fatigue, barrier of living and task performance decline. The data for empirical analysis were collected 401 responses on SNS users in Korea. The results of this study are as follows; First, reputation perception, loneliness, unwanted relation, privacy concern, information overload, social presence and interaction are significantly related to SNS fatigue. Second, SNS fatigue, barrier of living and Task performance decline are significantly related to discontinuous usage intention. Third, the moderating effect of Habit of SNS using is found in the relationship among SNS fatigue, barrier of living and task performance decline. Based on the results of this study, Theoretical and practical suggestions were discussed.

본 연구는 국내 대학생을 대상으로, 개인의 SNS이용과 사회적 지지 간의 관계에서 SNS 친구들의 반응 및 자아 존중감의 조절효과에 대해 살펴보았다. 전국의 대학생(여학생 N = 264, 남학생 N = 239)을 대상으로 실시한 설문조사자료를 활용해 회귀분석을 실시했다. 그 결과 SNS이용의 주효과는 나타나지 않았으나 SNS 친구들의 반응성 인식은 사회적 지지 인식에 대해 강한 주효과를 보였다. 또한 SNS 이용, SNS 친구들의 반응성 인식, 자아존중감 간의 삼원상호작용 효과가 나타났는데, 즉, 자아존중감이 낮은 대학생들 사이에서만 SNS 이용과 SNS 친구들의 반응성 인식 간의 상호작용 효과가 나타났다. 이러한 본 연구는 기존의 이론을 정교화하는데 기여하며, 대학생을 대상으로 한 SNS 기반 심리적 정신건강 중재 프로그램 설계를 위한 함의를 제공한다.

본고는 SNS의 구조에 나타난 클래식 게임 모델의 게임성을 증강, 퇴화, 역전과 부활로 구성된 맥루한의 테트래드 개념을 통해 분석하였다. 분석결과, SNS는 현실 세계의 플레이어가 자신의 주관과 이상적 경험을 가상 환경의 표현 규칙을 통해 실현하는 게임적 매체임을 확인하였다. SNS는 표현과 조작 규칙의 강화를 통해 게임성을 파이디아의 방향으로 역전시키고 있었으며, 플레이어의 노력 및 결과의 현실 영향력에 관한 협상 가능성을 퇴화시켜 보다 많은 플레이어들이 창조적 세계를 쉽게 구축할 수 있도록 진화하고 있었다. 또한 증강된 게임성으로 플레이어와 게임 간의 애착이 강화되었으며 추상적 공간에서 묘사를 통해 세계를 창조하는 MUD 전통을 부활시키고 있었다. 이상의 분석 결과에 근거하여 SNS가 현실에 한정된 실용적 소통매체에서 나아가 현실을 근간으로 플레이어의 다양한 상상과 가능성을 창조하는 게임적 매체임 확인한다.

With widespread use of smart phones, SNS has been growing rapidly. Companies are required to do its utilization and a preemptive response. However, taking advantage of SNS is still insignificant in the companies. Compared with traditional marketing, people still consider the SNS marketing unfamiliar. This study is aimed at widening the breadth of understanding of marketing activity using SNS and inquiring into its effective applications. In an effort to achieve this research objective, first, this study analyzed the aspect of real applications by reviewing diverse practical business cases. Second, this study provided the momentum of the understanding of SNS marketing-based knowledge. The effective method of producing consumer-intimate products and services lies in customers' participation in development and production. SNS marketing is the very communication and gives ear to a customer's voice. Earnest and creative SNS marketing will play a role as a stepping-stone for businesses to move much closer to a customer.

Recently, effort to obtain various information from the vast amount of social network services (SNS) big data generated in daily life has expanded. SNS big data comprise sentences classified as unstructured data, which complicates data processing. As the amount of processing increases, a rapid processing technique is required to extract valuable information from SNS big data. We herein propose a system that can extract human sentiment information from vast amounts of SNS unstructured big data using the naïve Bayes algorithm and natural language processing (NLP). Furthermore, we analyze the effectiveness of the proposed method through various experiments. Based on sentiment accuracy analysis, experimental results showed that the machine learning method using the naïve Bayes algorithm afforded a 63.5% accuracy, which was lower than that yielded by the NLP method. However, based on data processing speed analysis, the machine learning method by the naïve Bayes algorithm demonstrated a processing performance that was approximately 5.4 times higher than that by the NLP method.

Purpose Although companies occupied the network market take the advantageous position first and can be successful in securing users over a certain size, it is important to satisfy the customers' demand and prevent the outflow of users toward a new alternative SNS. What is more, there are frequent changes in the flow of users toward new SNSs. Despite these dynamic market circumstances, there is a lack of research to explain the switching behaviors of SNS users. Design/methodology/approach The objective of this study is to explain and verify a specified migration theory(Push-Pull-Mooring model) focused on SNS fatigue in the psychological point of view, as well as reviewing previous studies on functional and technical characteristics of SNSs themselves. Moreover, this study tried to highlight factors affecting users actual SNS switch rather than their switching intention. Findings According to the statistical analysis, the most influenced pull factor to switch SNS was the alternative attractiveness. On the other hand, undesired relationship burden, service innovation and important mooring factors to prevent users' SNS switch. This study has a significant contribution to the theory, which analyzed users' actual SNS switch, and examined SNS users' psychological factors(SNS fatigue), reviewing the characteristics of existing services. To secure more users and to keep them, companies providing social network service need to develop differentiated strategies by analyzing psychological characteristics of various users.

본 연구에서는 계획된 행동이론을 적용하여 SNS 이용에 대한 태도, 주관적 규범, 지각된 행동통제가 SNS 이용에 어떠한 영향을 미치는지를 분석하고, SNS 이용이 결속적 네트워크와 교량적 네트워크라는 사회적 네트워크 유형에 각각 어떠한 영향을 미치는지를 분석하고자 하였다. 이들 간의 관계에서 성별에 따른 조절효과를 검증하였다. 이를 위해 SNS의 주 이용계층인 20~30대 이용자들을 대상으로 한 설문조사를 토대로 실증분석을 실시였다. 구조방정식에 의한 가설검증 결과, SNS 이용에 대한 태도와 주관적 규범, 그리고 지각된 행동통제는 SNS 이용에 각각 정(+)의 영향을 미치는 것으로 나타났다. 또한 SNS 이용은 결속적 네트워크, 교량적 네트워크에 각각 유의미한 정(+)의 영향을 미치는 것으로 나타났다. 성별에 따른 조절효과를 분석한 결과, SNS 이용 영향요인과 SNS 이용 간에는 성별에 따른 유의한 차이가 없는 것으로 나타났지만, SNS 이용과 사회적 네트워크 유형 간에는 성별에 따른 유의한 차이가 있는 것으로 분석되었다. 이러한 분석결과를 토대로 본 연구에서는 SNS 이용과 사회적 네트워크에 관한 이론적 실천적 함의를 제시하였다.

SNS는 양방향 소통, 인맥관리, 정보 전달 등의 기능을 하는 사회적 연결망 서비스로써 국내 외 SNS 시장은 지속적인 성장을 해왔으며, 최근 그 성장세를 가속화하고 있다. 이러한 환경에서 미성숙한 학생들은 부정적인 사이버행동을 할 가능성이 크다. 본 연구에서는 초 중학생들의 SNS 사용실태와 사용동기, SNS의 적극적 기능사용 정도, 의존경향성, SNS에 대한 인식과 SNS에서 이루어지는 부정적 사이버행동과의 관계를 알아보기 위하여, 부정적 행동의 경중에 따라 4단계로 나누어, 각 단계별로 요인값의 분포 차이를 조사하였으며, 연관규칙 분석을 통하여 단계를 결정하는 요인값들의 조합을 구하였다. 연구결과, 부정적 행동을 거의 하지 않는 학생들이 85%나 되었고, 가장 많이 행하는 부정적 행동은 개인정보도용과 낯선이 접촉이었으며, SNS에의 의존성이 높은 학생들은 부정적 행동을 많이 할 확률이 크다는 것을 확인하였다.
